Design tailored for specific uses achieves overwhelming weight reduction! Approximately 1/2 the weight (compared to conventional models)!
The "DVF (Open/Close-kun)" is a valve-integrated fitting born from the innovative idea of "giving fittings a valve function." While maintaining the same structure and functionality as the conventional metal diaphragm valve DVF series, it achieves an overwhelming weight reduction of 50% compared to traditional products. It is suitable for high vacuum, high durability applications and can be used in manufacturing lines that require ultra-pure fluids, flammable, or toxic fluids (such as in the semiconductor field, bulk gas, and high-purity gas applications). It is designed for small diameter piping. *For more details, please download the materials or feel free to contact us.*

Company information
We are a company that scientifically studies "optimal piping" for all fluids across all industries. We also manufacture optimal fittings and valves for this purpose. Fittings and valves are part of the piping, and we take pride in being a "science manufacturer" that seriously considers how to make fluids flow more "efficiently." We design, process, assemble, and maintain piping, seeking "optimal" solutions from various perspectives, thinking about them, and bringing them to life. With a commitment to and pride in piping, we provide our customers with "optimal piping."
